Do I Prep after Sanding Deck? 5/5 (1)

Clean after Sanding Deck?

Yes, after sanding, it is suggested to lightly clean and brighten the wood. This will help open the wood grain so the stain can dive even deeper into the wood. Better penetration = better stain performance!

Key takeaways
  • After sanding, lightly clean and brighten the wood to open the grain for deeper stain penetration.
  • Better stain penetration leads to better overall stain performance on your deck.
  • Sanding removes raised wood fibers left behind from power washing and opens the wood pores.
  • Use the correct sanding grit of 60 to 80 for best results on a wood deck.
  • A higher sanding grit can make the surface too smooth, closing down the pores of the wood.
  • Closed wood pores make stain absorption harder and can lead to premature stain failure.

Sanding Deck Tips

Sanding removes any raised wood fibers from power washing and opens the pores of the wood to assist in soaking in the stain or sealer. It is important to use the correct sanding grit on your deck. The recommended sanding grit is 60 to 80. This is because a higher grit could make the deck too smooth, and will close down the pores of the wood. Closed pores make it more difficult for the stain to be absorbed and could lead to premature stain failure.
